Yosuke isn't entirely sure how to feel about that. It's not like he's never fantasized about a hot girl back in high school during class, but it's weird to hear that the teacher was doing it, even if it is Yu.

"Wooo, never knew you were such a horndog, partner..." He says in jest, because it's still cute that he's being thought about even while Yu is at school teaching, and he appreciates it. "You're not gunna let it slip to the whole class on accident one day, are you? Give it the good 'ol Freudian slip?" He laughs, poking fun. And proud of himself that he remembered that from school.
